Genome-wide identification and expression analysis of the calmodulin-binding transcription activator (CAMTA) gene family in wheat (Triticum aestivum L.).

Background: Plant calmodulin-binding transcription activator (CAMTA) proteins play important roles in hormone signal transduction, developmental regulation, and environmental stress tolerance. However, in wheat, the CAMTA gene family has not been systematically characterized.

Results: In this work, 15 wheat CAMTA genes were identified using a genome-wide search method.

Transcriptome analysis of activated charcoal-induced growth promotion of wheat seedlings in tissue culture.

Background: Activated charcoal (AC) is highly adsorbent and is often used to promote seedling growth in plant tissue culture; however, the underlying molecular mechanism remains unclear. In this study, root and leaf tissues of 10-day-old seedlings grown via immature embryo culture in the presence or absence of AC in the culture medium were subjected to global transcriptome analysis by RNA sequencing to provide insights into the effects of AC on seedling growth.

Results: In total, we identified 18,555 differentially expressed genes (DEGs).

Homoeologous cloning of omega-secalin gene family in a wheat 1BL/1RS translocation.

Wheat 1BL/1RS translocations are widely planted in China as well as in most of the wheat producing area in the world for their good qualities of disease resistance and high yield. 1BL/1RS translocations are however poor in bread making, partially caused by a family of small monomeric proteins, omega-secalins, which are encoded by genes on 1RS. Based on published sequence of a rye omega-secalin gene we designed a pair of primers to cover the whole mature protein coding sequence.
